This invention relates t what vis often V l1@ facture, particularly inso far as ease of proper assembling of the elements entering into thedevice is concerned, and which possesses certain other advantages aswill hereinafter more clearly appear from the followm ing descriptiontaken in connection with the accompanying drawing, in which- Fi 1 is afragmental plan view of a tape Thesel pockets are equally spaced fromone another in both tapes, and are of-such dimenslons, particularly .inso far as the space afforded between their respective ends is con*cerned, that they snugly receive a series of 55 snap-fastening elements10 and 11, respectively, the vfastening elements 10 and 11 of eachpairof such being complementary and constituting a standard separablefastener. Of course, however, tape havin are open at both ends mighteused. l

Referringeio the fastener elements 10, each includes a base 12 whichengages the ends and bottom of any one of theA pockets 7 when it isintroduced into the same, the base being pro- 65 'vided with aprotruding portion 14. The protruding portions 14- of the fastenerelepockets which 60 of fa ric, in which are incorporated a pluralityof'similar elements of a plurality of standard separable fasteners;

Fig. 4 is an enlarged fragmental View, showing a portion of the tape offabric of Fig. 2 in association with one of the fastener elements ofthat tape; y Fig. 5 is a transverse sectional view taken on line 5--5 ofFig. 3, the fastener element being shown in elevation, and

Fig 6 is a transverse sectional View taken on line 6 6 of Fig. 4, thefastener element being shown in section.

The improved separable fastening device embodying this inventionpreferably includes a pair of tapes of fabric 5 and 6, each of which iswovenaccording to well-known methods in the weaving art-to provide aplurality of pocket-s 7 and 8, access to which may be had from one vedgeof the respective tapes, as I shown most clearly in Figs. 5 and 6, andeach of which extends transversely of the tape in which it is formed towithin a definite distance from the opposite edge of that tape.

ments 10 project through apertures-15 formed,

as by a piercing operation, in a side wall of the respective pockets 7incident to which 70 piercing operation a similar aperture a may beformed in the adjacent side wall of the respective pockets. As to theaperture 15a, it is without utility; but, on the other hand, it iswithout objection, inasmuch as it 75 will lie neXt to that part of thegarment to which the tape 5 is sewed and will be concealed. As to thelocation of the aperture 15,

it will be noted that' they are so positioned, with respect to the endsand the bottom of the 9@ respective pockets 7 and with respect to thebase portion 12 of the respective fastener elew ments 10, that theyalign with and, therefore, readily receive the protruding portions 14'of the fastener elements when such elements are 85 introduced into thepockets far enough to engage the respective bottoms thereof. Because ofthe dimensional relation of the base l2 of the respective fastenerelements 10 to the respective pockets 7, and because of the fact that 9@the protruding portions 14 of these fastener elements project throughthe apertures 15, it follows that the fastener elements 10 so fit thesepockets that they are held against shifting longitudinally of the tape 5in either di- 95 rection and transversely of such tape in a direct-ionaway from'the entrance end of the pockets 7 In order positively toretain the fastener elements 10 against shifting transversely in anopposite direction, that is in a 00 direction toward the entrance end ofthe respective pockets, the side Walls of such pockets 7 are preferablysecured together as by paste'or stitching adjacent the entrance endsthereof and immediately adjacent the base portion 12 of the respectivefastening elements, such stitching beingindicated as 16 and shown asextending throughout the length of the tape, although of coursestitching limited in length to the respective pockets may be employed ifdesired.

From Figs. 2, 4 and 6, it Will be evident that the fastener elements 11each include a base portion 12 and a socket portion 18, the entrances towhich socket portions register a size substantially equal to theentrance to" With apertures 15, which are formed, respectively, in oneWall of each pocket 8 of the tape 6 by a piercing operation, as

described in connection4 with the apertures,

15 in the tape 5 of Figs. 1, 3 and 5. The ap ertures 15", are of a sizesubstantially equal to the entrance tothe socket portions of thefastener elements 11, so that the vfastener elements 11 aresubstantially covered a-nd concealed on that side of the tape, by theapertured Walls of the pockets.v Thus a neat and attractive appearanceof the tape l 6, with its associated fastener elements, is

presented. The closed ends of the socket portions 18 form projectionswhich extend rear- Wardly of the base portion 12 and through theapertures 15a in the tape, as shown in Fig. 6. These projections thusserve to retain the fastener elements 1l against displacement. Also, itis to be noted that, since the apertures 15a accommodate theprojections, the overall thickness of the tape 6 in the vicinities ofthe pockets 8 may be kept at a minimum,

inasmuch as the side Walls of the respective pockets 8 in which theapertures 15a are formed is not required to overlie the projection ofthe socket portions 18. lFrom Figs.

4 and 6, it will be noted that the fastener elements 11 are held, (asare the fastener elements in the tape 5) against shifting longitudinallyof the tape 6 in either direction and transversely of such tape in adirection away from the entrance end of the pockets 8. In

ordei` positively to retain the fastener elements ll'against shiftingtransversely toward the entrance lends of the respective pockets 8, theslde walls of such pockets are preferably*- secured together adjacentthe base portion 12 of the respective fastenerelements, as by` glue orthe stitching indicated at 16. The necessity for maintaining thefastener elements 11 against displacement will be appreciated froml thefact that the aperture must be maintained at all times in registrationwith the entrance to the socket portion 18 of the festem. er element soas to permit thereception oftheprotruding portion 14 of thecomplementary fastener elementlO. Y A

When the apertures 15 and 15? are formed,

as by a piercing operation, certain'of the threads of the tape are, ofnecessity, broken or severed, thereby rendering the tape likely to ravelat or in the vicinity of the apertures.

In order to obviate such raveling, a suitable 7 sary, a similar sizingoperation may be like- Wise carried out with respect to the apertures15a and 15a.

From the foregoing, it will be understood .i

that the snap tape herein shown and described possesses the importantadvantage, among others, of being easily and economically manufactured.When'the fastener elements are introduced into the pockets, they areeasily so positioned that the protruding portions 14 of the fastenerelements 10 enter the apertures 15; and so that the projections of thefastener elements 11 enter the apertures 15a. Thus a great saving intime is effected in the assembling operations, over the time that Wouldbe required were it neces\ sary to exercise any great amount of care in`properly inserting and positioning the fastener elements preparatory topermanently securing them in the respective pockets. Furthermore, whenit is thought advisable to positively secure the fastener elements inplace by closing the openings in the pockets as above described, thefastener elements are restrained from movement transversely of the tapeduring the pasting or stitching operation.
